I don't know of any newer benchmarks. However, I'm reading the results differently I guess, because the results show that with 128 threads, modules become slower only when the DAG depth is higher than 29, and that's quite a large depth! It also looks like each source file used in the benchmark only imports other modules and declares 300 variables, but nothing else. Practical workloads will have more interesting stuff in the source files, so I would expect the impact of module loading to be less, so more can be done in parallel.
